TQ ALL WHOM IT MAY CONOERN:

I Be` it known that I, JOSEPH RYAN, of the city and county of St. Louis, State of Missouri, have invented-a new and improved Scuttle-Iloor for Vessels, Buildings, Dry-Docks, Btc.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. Of said drawings- I Figure 1 is a general plan, showing the application of my improvements to therdeck or door of a vessel.

y Figure 2 is a plan, showingthe under side of a deck and the arrangement of a scuttle-door, with lock and water-injection hose. l A Y Figure 3 is a sectional elevation, showing the scut-tleLd-oor and its mode o f fastening to thedeck, roof, or door, and also the general manner of joining the deck or roof planking.

Figures 4 and 5 show in 'detail the jointing of the planking on length seams; and

Figure 6 shows in detail the transverse or end seams of the planking.

Firstly, the nature of my invention consists in the application of one or more safety or scuttle-doorsto the decks of shipping, dry-docks, 5to., or floors or roofs of buildings, arranged to permit an'inspection of enclosed spaces, and to permit the application of the usual means for extinguishing tires; said scuttles being, moreover, made water or fluide-tight, and' with locks to prevent the entrance of unauthorized persons.

To-enable those skilled this art to make and` use my said improvement, I will now proceed-to describsi-ts construction and operation; and in this description I will specially describe the application of'my said improvement to the decks' of vessels intended for use on waiter, this being the application of said improvements which will be in more general use and of morev general benefit; but I do especially state that my said improvements may and do find useful application to buildings generally in the same manner as to vessels on water service.

At such points on the deck A of a vessel, where it would be useful to gain access to parts otherwise inaccessible or inconveniently accessible, I construct the safcty-door or -scuttle B, usually of some non-corrosive metal, like brass. The scuttle B consists of the frame C and the door D. rEhe parts arelso arranged with reference to the surface'of the deck A as not to-protrudc, the deck planking being cut out to receive the fram'o C,Vso that their upper surfaces are in the same plane, and the door D resting when closed similarly in the frame C. The joint between the frame C and A I- secure in a perfectly water-tight manner. The frame C is secured -against A by screw-,bolts c passing fr'om the under side of A, and screwing intoproper bosses on the lower side of C, as at el, said bolts c being arranged so as in nowise to reach the upper surface of C, so that under all contingencies of wear or injury the upper surface of C above said bolts e shall remain intact, therebypreventingall danger of Water leakage at these points. To prevent the bolts c fromcutting' into the contact surface .of A, a washer, ye2, may be inserted between said surface of .A and the head of the bolt. The doorD is connected with the frame C by means of proper hinges",` substantially as shown. When the door is shut down it is retained securely in its seat in the frame by a lock, E, which maybe made of a bolt, e, spring ehosaidgbolt being moved by a key, Land upon withdrawal of the key being forced out by said spring el, or of any equivalent devices. In the arrangement shown the bolt e enters a proper mortise in the frame C whenem the door is dropped into position without the application ofthe key;v the key, moreover, is used t0v raise the door. Should the door be heavyya handle may be conveniently attached to D. vThe door D is of such size as to permit the passage of a man, or it may he larger, permitting the passage of goods, Ste.

Whenever it becomes advisableer necessary to inspect or repair any apartment of a vessel Or building, the design here is to permit such inspection or repair by the passage of Aan operative through said door D. This is of especial importance in ships where certain apartments may foul or become leaky or be otherwise injured, when the samerwould not be accessible, or not easily accessible, from the main hatches er gangways. To prevent great dam-nge and danger' by fires, I have arranged the cap-nut d, closing an opening, dl, in D.V VA boss on the-lower `*surface of D receives thehcse etz, and this has the nozzle di. Insaid nozzle a series of hlesl permit Water to pass out of the nozzle and pass in all directions in the apartment below and surrounding.' When, therefore, it becomes necessary to extinguish flames, a connection can be quickly made, (after the nut d has been removerh) the interior surface oi' d1 being arranged with screw-threads to secure the cap-nut` d; these maybe used to secure a proper nozzle of the supply hose. In this wise the introduction of water for 4.extinguishingfires may be quickly'and einen 2 eeetu'ally made, anni at the same time en exclusion of aix', which is almost perfect, be attained, thereby greatiy lessening'the damage and`dangerfrom {ires in unepproachabie apartments. Another mode of introducing a large solid stream of Water is indicated by red lines in fig. 3. The supply hose is here simply connected with a heut nozzle, cl, (whioh is so bent as to pass from above through the opening d.) This nozvzle cam'by nnnnipue` lating the supply hose, easily be tnrned'so as to throw a stream in all the directions needed.

Having thus fully desoribed iny invention, what I cla-im therein as new, and desire to secure by Letters Patent, is

The combination andermngement of :L scuttle-door, B, having one or more {ire-safety openings di, and conducting,` and distributing hose oi' pipes d2 ds ol, with decks, roofs, SLC., substantiaiiyin the manner and'for the purposes herein set forth.

JOSEPH RYAN.
